For Environmental Engineering 6th Sem scheme and its subjects, do visit Env 6th Sem 2021 regulation scheme. For Professional Elective-IV scheme and its subjects refer to Env Professional Elective-IV syllabus scheme. The detailed syllabus of surface and groundwater quality modelling is as follows.

#### Unit I

MODELING PERCEPTIONS Engineers and Mathematical Models-Water quality models – Historical development – Different types of models– Steps in model development – Importance of model building. – Calibration and verification of models- conservation of mass and momentum – Chemical reaction kinetics – Law of mass action, Rate constants, reaction order, types of reactions, equilibrium principles.

#### Unit II

POLLUTANT TRANSPORT AND REACTOR MODELING Transport phenomena – Advection, diffusion, dispersion- simple transport models – Plug flow models- Application of PFR and MFR model – Steady state and time variable solutions-completely mixed systems, concept and models in Completely Stirred Tank Reactors, mass balance equations, loading types, feed forward vs. feedback reactor systems

#### Unit IV

GROUNDWATER QUALITY MODELING Groundwater flow and mass transport of solutes, Degradation of organic compounds, application of concepts to predict groundwater contaminant movement, seawater intrusion -basic concepts and modelling

#### Unit V

WATER QUALITY MODELING SOFTWARE Exposure to surface water and groundwater quality modelling software – MIKE 21, QUAL2E and MODFLOW Models and their application, Case studies.

#### Course Outcomes:

1. Know about the principles of water quality modelling.
2. Understand the pollutant transport phenomena in surface and groundwater.
3. Apply the knowledge of surface water quality modelling to predict the water quality of rivers, lakes and estuary.
4. Predict the groundwater contamination transport.
5. Predict water quality of surface and sub surface water using numerical solution.
